The present disclosure is related to articles (e.g., containers, battery packs, etc.) including a lithium material (e.g., one or more lithium-containing batteries) housed therein. The articles include sulfur hexafluoride located within an interior compartment of the article to provide an inert atmosphere within the interior compartment. The present disclosure is also related to methods of inerting such articles (e.g., containers, battery packs, etc.) with sulfur hexafluoride. Additionally, the present disclosure is related to conveyed (e.g., pumped, blown, etc.) looped cooling apparatuses and systems.

Methods of inerting lithium-containing batteries and associated containers

A method and apparatus for launching a space vehicle. Operation of a first portion of a plurality of rocket engines associated with a space vehicle is started such that a flow of a gas is initiated through a duct system under the plurality of rocket engines. The gas is located in an area near the plurality of rocket engines. Operation of a second portion of the plurality of rocket engines associated with the space vehicle is started after the flow of the gas begins traveling through the duct system to launch the space vehicle.

A solar powered radiometric lift device operable to generate sustained lift is disclosed. A hot surface powered by solar energy and a colder surface are utilized to generate a pressure differential via free molecular momentum exchange. An insulating space may be situated between the hot surface and the colder surface, and formed into channels allowing thermal transpiration. The solar powered radiometric lift device is operable to provide sufficient lift for a geostationary stratospheric platform. Embodiments of the solar powered radiometric lift device are further operable to provide station keeping thrust and controllability.

Solar powered radiometric lift device

A pressure oscillation damping mechanism comprises a cavity having an entrance exposed to fluid flowing on an exterior of the cavity. The damping mechanism may include a constriction positioned adjacent to the entrance and being sized to dampen an amplitude of the pressure oscillations occurring within the cavity.
